Application illed April 16, 1817, Serial lilo-182,888. Renewed February 3, 1920. Serial No. 8l55,855.

To all whom it may concern: 4 Be it known that I, FRANK H. SILVER: THORNE, a citizen of the United States, and resident of New York cit in the county of New York and State of ew York, have in? vented certain new and useful Improvements in Bottle-Stoppers, of which the following is as cificatlon.

My invention relatesito a receptacle closure of the wedging t and particularly relates to such a closure designed to close bottles and other frangible and easily breakable parts.

In devices of this class now known it has been necessary either to provide the bottle with some particular form of neck, usually a rimmed construction, so as to accommodate the closure, or the closure had to be applied by machinery to effect it necessarily permanent sealing.

These particularly formed bottles are expensive to construct, and the machine se cured closures are removed only with difliculty, and after removal are usually of no value fora subsequent closing. 0

Primarily the object of my lnventlon is to provide a simple form of closure which can be quickly wedged into position on a plain rimmed bottle or other receptacle.

Another object of the invention is to provide a simple and inexpensive form .of closure which can be readily forced on or demounted from the bottle by manual operation and which will hold simply by frictional tension and which will insure a secure closing of the bottle either temporarily or when packed for transit.

I attain this object broadly by providing a holding shell of non-elastic material and fitting a ring of compressible material in said shell. The bore of the ring at the bottle engaging end is somewhat reduced and.

provide a simple form of bottle closure for insuring the sealing not only of the liquid This object is attained simply by posit 1 oning a thin liningof compressible material between the inner edge of the ring and the top wall of the shell Various other objects and advantages of the invention will be in part obvious .from' an inspection of the accompanying drawrugs and in part will be more fully set forth 1n the following particular description of one form of mechanism embodying my invention, and the invention also consists in certain new and novel features of construction and combination of parts hereinafter set forth andclaimed.

In the accompanying drawings- Figure 1 is an axial sectional view through a bottle top showing a preferred embodiment of and Fig. 2 is a similar view of the closure shown in Fig. 1 and detached from the bottle. I

In the following description and in the claims, parts will be identified by specific names for convenience of expression but theyare intended to be as generic in their application to similar parts as the art will perm1t.

In the drawings there is shown a bottle neck 3 on the top of which is mounted a cast porcelain pour-out member 4 fixed to the bottle by a securing flange 5. The pourout is provided w1th a liquid pouring passageway 6 and an air-inlet passageway 7 usual In one known type of such constructhe subject-matter of this invention is in the form of a top designed to telescopically fit the cylindrical portion of the receptacle and comprises an outer containing shell 9 preferably of metal and stamped to shape. The shell includes a cylindrical wall 10 and an end or top wall 11 integral therewith. Fitted within the shell and engaging the cylindrical wall thereof is a ring 12 of some readily com ressible material, suchas cork, which ring is of a sum to firmly engage the inner face of the wall 10 and is practically co-extensive therewith. This ring is provided with a centrally disposed bore 13 extending therethrough from end to end and having a diameter substantially equal to the diameter of the cylindrical part 8 engaged thereby.

This ring is particularly characterized by the fact that the lower end 14 thereof is of slightly greater thickness than the upper portion thereof, thereby to form the bore into a frusto-conical form, with the small end disposed outwardly or at the bottom of the closure, as shown more particularlyin Fig. 2. In this figure the thickness of the lower portion of the ring compared with the upper portion has been purposely exaggerated in order to show that the diameter at the lower portion of the cap was slightly smaller than the diameter at the upper portion. In its commercially perfected form there will be but very slight difference between the diameter at the upper end compared with the diameter at the lower end of the ring. A disk 15 ,of some suitable closing material, such as cork, is disposed between the upper end of thering and the. adjacent top wall of the shell. The disk 15 is particularly designed to not only close the passageways 6 and 7 from the outside, but is particularly of value to secure a complete closure between the passageways 6 and 7. In operation it will be understood that the closure is forced manually onto the cylindrical end of the receptacle, which action will tend to cause the material at the outer end of the ring to be compressed and distorted inwardly toward the upper portion adjacent the disk 15. The lower end of the ring 1.2 has a relatively lighter frictional engagement with the cylindrical portion of the receptacle, than the upper end thereof. This construction has a tendency to distrib ute the distorting strains on the lower end of the ring uniformly along the entire length of the bore, thus insuring a firm, frictional engagement between the closing member and the cylinder for substantially the entire length of the cork ring.

It has been found that this form of 010- sure is possible of being inserted on and withdrawn from its closing position by simple manual pressure and pull yet is peculiarly effective in hermetically sealing the bottle just as effectively as the usual cork stoppers.

While I have shown the described, and have pointed out in the annexed claims, cerincense tain novel features of my invention, it will be understood that various omissions, substitutions and chan in the form and details of the device i lustrated and in its operation may be made by those skilled n the art without departing from the spirit of the invention.

Having thus described my invention, I claim 1. In a device of the class described, the combination with ac lindrical bottle neck, of a closure for said neck, said closure including a cylindrical containing shell surrounding the neck, and a ring of compressible material disposed between the neck and shell, one end of the bore of said ring being normally of a diameter slightly less than the diameter of said neck and the bore at another place normally having a diameter slightly greater than the diameter at said end and approximately equal to the diameter of said neck, whereby the material of the ring at one place is of greater thickness than at another place and is designed to be crowded toward said other place when the neck is forced into the bore of the coinpressible ring.

2. A closure includinga cylindrical flange, and a sealing ring having a material length compared with its diameter and fitted within said flange, the wall at one end of said ring being thicker than the opposite end and converging in thickness toward the opposite end thereby to form a frusto-conical bore to the ring.

3. A closure comprising an outer cylindrical shell of non-elastic materialand provided with an open end, and a compressible lining ring fitted within the shell the wall of the ring adjacent the open end of the shell being of greater thickness than at the opposite end and forming a frusto-oonical bore adapted to engage a bottle neck along the entire length of the bore.

i. A closure for receptacles including a receptacle engaging member in the form of a ring of compressible material and provided with a bore adapted to receive and frictionally engage the receptacle when the member is telescoped thereon, one end of said bore being closed and the other opened said bore being smooth and having a diameter at itsopen end less than its diameter at the opposite closed end.

Signed at New York city, in the county of New York and State of New York, this fifth day of April, A. D. 1917.
